If you go into the climate settings and press the three dots, it opens up a screen to turn the heater window element on at the bottom of the screen, this aids by heating up the wipers at the bottom of the screen. I do this and hit the front screen button.
It’s never going to be as quick as my last car with the heated elements in the entire front windscreen, but the heated element does actually help the wipers clear frost off the window a little bit Worth a try!
